Nukuhou saltmarsh and Ohiwa care groups
Ohiwa Reserves Care Group
The Ohiwa Reserves Care Group has looked after Whangakopikopiko
(Tern) Island and the Ohiwa Domain for several years. The Island is
an important breeding place for rare birds such as the white
fronted tern and Northern NZ dotterel. There is extensive predator
control on the Island and predators, including stoats and rats, are
controlled through trapping. The Group also carries out trapping in
Students from Waiotahe School are also regular helpers on the
Island. They have planted native plants, including the rare
'Thornton' kanuka, which is native to the Island.
Care Group helps whitebait and birds
The Nukuhou Saltmarsh Care Group at Cheddar
Valley has actively cared for the saltmarsh and the nearby river
mouth since 2003.
Fernbird and banded rail numbers have increased dramatically as a
result of the Group's predator-trapping activity. During the last
seven years, the Group has trapped 167 stoats and 88 weasels around
the margins of the saltmarsh and fernbird numbers have more than
doubled as a result.
The Group recently dug swales, or ditches, beside the Nukuhou River
near the 'S' bend at Cheddar Valley, to provide a spawning area for
The team has also built a riverside walkway, constructed an
interpretation point and a board walk into the marsh and planted
hundreds of native plants through the area.
The next project is to carry out pest control on Uretara Island
in conjunction with DOC and local iwi.
